OK, How about Dry Suits?

[Chris H]

Define limited money.    Based on how much you use it, a good drysuit should last many years and several hundred dives.  I had my first suit for about 10 years.  My first was a Typhoon, which I don't think you'll find in the US.  I now have a Bare Trilam-HD.  Many of my friends have DUI suits.  There have been some discussions on this board about suits.  Do a search and see what you come up with.
